Specification of Letters Patent.

Patented Mar. 5, 1918.

Application filed April 13, 1917. Serial No. 161,889.

To all whom it may concern Be it known that I, ALBERT 'Fnarrnss, a citizen of the United States, residing at Chesterton, in the county of Porter and State of Indiana, have invented new and useful Improvements in Current-Deflectors for Marine Vessels, of which the following is a. specification.

The present invention relates to improvcmerits in means for facilitating the travel of bodies, such as vessels, torpedoes, etc, in the water.

In carrying out my invention it is my purpose to arrange on the bow of a marine vessel, a torpedo or the like, a nose member so constructed and arranged as to provide a deflector for the currents of water through which the body travels, to have a cutting effect upon the water through which the body travels and to direct the said Water lZl'l't'Ollgll the nose member to the opposite sides of the bow of the body, consequently reducing the force of obstruction by the water and assisting in n'laterially increasing the speed of the body or vessel. I

It is a further object of the invention to produce a deflector which may be formed with a vessel in the construction thereof or which may comprise a separable member that may be easily attached to or detached from the vessel.

It is a still further object of the invention to produce a device of this character which shall embody the desirable features of simplicity, cheapness and etliciency.

lVith the above and other objects in view the improvement resides in the construction, combination and arrangement of parts set forth in the following specification and fall.- ine' Within the scope of the appended claims.

In the drawings:

Figure 1 is a perspective view of a portion of the bow of a marine vessel provided with the improvement,

Fig. 2 is a horizontal. sectional view ap proximately on the line 2-2 of Fig. 1,

Fig. 3 is a vertical transverse sectional view approximately on the line 3-3 of Fig. 1,

Fig. is a side elevation of the lJOW of a submarine vessel or torpedo provided with the improvement.

Fig. 5 is a horizontal sectional View approximately on the line 5-5 of Fig. i

Fig. 6 is a vertical transverse sectional view approximately on the line 6-6 of Fig. 4,

l? 7 is a top plan view illustrating a modification,

Fig. 8 is a side elevation of the same, and

Fig. 9 is a sectional view approximately on the line 9--9 of Fig. 7.

The improvement is designed for use upon all classes of marine vessels, torpedoes or the like, and in the drawings, and referring particularly to Figs. 1 to 3 thereof, the numeral 1 designates the bow of a vessel of any or iliuary construction. having my improvement applied thereto.

The nature of the improvement is such as to render the same subject to modifications as to shape, size, etc, to accord with the class of vessel or other object upon which it is applied, and the improvement may be made as part of a vessel in the construction of such vessel or may be in the nature of a separable element that may be applied to the vessel after the construction of said vessel. lVhen the improvement is employed upon comparatively small craft or objects, the same is secured to the top and bottom thereof, the lower portion of the improvement being in a line With or above the keel of the vessel and the upper portion being above the Water line of the vessel. The improvement is preferably constructed of metal but, of course, may be constructed of any other desired material so treated. as to render the same not liable to disintegration from the influence of the water, and, of course, of suliicient strength and rigidity to Withstand the strain to which it is subjected. In the referred to Figs. it to 3 of the drawings the nose or deflector member includes a bottom plate 2, a top plate a and angular side members 3 formed integrally with the top and bottom plates. The top plate a may be provided with a central slot or opening surrounded by an upstanding flange a and this flange engages with the opposite sides of the bow of the vessel 1 and is secured thereto, as clearly illustrated in Fig. 1 of the drawings, ivhile the bottom plate 2 may be arranged in a line with the heel of the vessel 1 and be riveted or otherwise secured thereto. The angular sides are disposed a suitable distance from the sides 5 of the vessel 1 providing a passage between the inner surfaces of the said sides 3 and the sides of the vessel. By reference to Fig. 2 of the drawings it
